Abstract：Myocardial bridging is a congenital variation of the epicardial coronary artery that the coronary artery segment is covered by myocardial fiber,which is most commonly observed at the left anterior descending branch(LAD).Myocardial bridging is generally considered as a benign lesion in the past.However,it has been found that myocardial bridging can lead to angina symptoms,acute coronary syndromes,arrhythmias and even sudden cardiac death recently.For symptomatic myocardial bridging patients,drug therapy is used first,but myocardial bridging supra-arterial myotomy is the best choice when the maximum tolerated dose drug therapy fails.The supra-arterial myotomy can significantly improve the score of 5 dimensions of Seattle angina questionnaire(SAQ)with high surgical safety and good prognosis of short-term and medium-term.This article provides a detailed review of the current application status of myocardial bridging supra-arterial myotomy in different populations and diseases which myocardial bridging comorbid with.It compares the differences among supra-arterial myotomy and other treatments in detail.It also summarizes the progress ofrelevant auxiliary technologies.
